UNITED STATES DANIEL HEWITT, OF FORT WORTH, TEXAS.

HIGHWAY vsnnim'n.

Application filed March 18, 1929.

My invention relates to signals and more particularly to signals for theintersections of highways, railway crossings or crossing of highways andrailways, and curves and the like; and the object is to provide signaldevices which will be automatically operated by the passing of thewheels of a vehicle over certain actuating devices and to providedevices which will be positive in action and which are simple inconstruction and operation and which will serve as warning against thepassage in case of danger. Other objects and advantages will be fullyexplained in the. following description and the invention will be moreparticularly pointed out in the claims.

Reference is had to the accompanying drawings which form a part of thisapplication.

Fig. 1 is a perspective view of a roadway and the signal devices mountedthereon.

Fig. 2 is an interior elevation of the signaling devices.

Fig. 3 is a transverse section of a road bed, showing the main actuatingbar.

Fig. 4: is a vertical section, taken substantially on the line 47-41: ofFi g. 3.

Similar characters of reference are used to indicate the same partsthroughout the several views.

The drawings show a portion 7 of a road bed having a transverse groove 6therein. A rod or pipe 5 is mounted partly in the groove 6 and projectsslightly above the road bed. The rod 5 is yicldingly supported in framemembers 1 and 2 which may be of concrete or other material. Rods 4, L-shaped, are operatively connected to the rod or pipe 5 and projectloosely through the upper sides of the frame members 1 and 2. Metallicplates 8 are attached to the upper side of the lower parts of the frames1 and 2 and the rods 1 project loosely through these plates 8. Theplates 8 protect the frame members against wear, and also form seats forthe springs 9. The springs 9 are mounted on the rods et and held thereonby nuts 10 and washers 11 form seats for the upper ends of the springs.The tension of the springs 9 may be controlled by the nuts 10. When avehicle runs over the rod 5, this rod will be depressed and after thepassage of the vehicle the springs 9 will restore the Serial No.347,762.

rod 5 to normal position to be engaged by the next passing vehicle.

Vertical brackets 14 are attached to the frame 1 parallel to the arms orrod 1 and knockers or clappers 13 are pivotally mounted in the brackets14 with ends projecting towards the rod 1. Across bar or pin 15 isrigidly mounted in the rod 4 and projects from both sides thereofadapted to strike the knockers or cla'ppers 13. Metallic disks orsounding devices 12 are suspended from the upper member of the frame 1in position to be struck by the knockers 13.

Then a vehicle runs 011 the bar 5, the bar 5 will be depressed suddenlycarrying the pin 15 which will actuate the knockers 13 and cause theknockers to strike the sounding devices 12. This will be done as oftenas a vehicle runs on the bar 5. The rods 14- are held againstdisplacement by the frames 1 and 2. Blocks 16 are mounted in the bottomof groove 6 to limit the down ward movement of the bar 5. These blocks16 may be made of any suitable material.

What I claim, is,-

1. Signaling devices for highway crossings comprising a depressible barand provided with vertically extended members, a guide frame for saidmembers and said members adapted to move freely in said guide frame,springs operatively associated with said members for restoring saidmembers to normal position after a depression, an actuating pin carriedby one of said members, sounding devices suspended from the frame onopposite sides of said pin, brackets attached to said pin carryingmember, and knockers pivotally mounted in said brackets having armsprojecting in the path of said pin and arms projecting under saidsounding devices and adapted to strike said sounding devices whenactuated by said pin.

2. Signaling devices for highway crossings, (the highway being providedwith a transverse groove,) comprising a depressible bar mounted partlyin said groove and pro jecting above the surface of the highway andprovided with upstanding guide arms, one arm being a signal actuatingarm, a rectangular supporting and guiding frame for one of said arms, arectangular signal-carrying frame for supporting and guiding said signalactuating arm, springs mounted on said arms and confined between themembers of'said frame for restoring'said arms and bar. to normalposition after a signaling operation, soundin devices suspended in said'5 signal-carrying frame, an actuating pin carried by said signalactuating arm, and knockers of clappers pivotally mounted in said signalcarrying frame and each knocker having one arm projecting in the path ofsaid pin and another arm adapted to strike 1 a sounding device whenactuated by said pm.

In testimony whereof, I set my hand, this 5th day of March, 1929.

DANIEL HEWITT.
